South Dakota Energy Adjustment and Riders

South Dakota electric service statements include an Energy Adjustment and two riders. For additional information please refer to specific rate schedules

The Energy Adjustment reflects the cost of fuel we use to generate electricity to serve our retail customers, transportation costs for that fuel, costs we incur to buy energy to supplement our own power plants, and costs of reagents and emission allowances. We pass along purchased-power and fuel costs without any markup to our customers.

As of December 2014 the Environmental Cost Recovery Rider (ECRR) allows our company to recover costs that we incur to meet federal environmental quality requirements for our electric generating facilities. The South Dakota Public Utilities Commission approved our request for an ECRR to include the costs associated with an air-quality control system (AQCS) at Big Stone plant in South Dakota and Mercury and Air Toxics Standards (MATS) at Hoot Lake Plant. The AQCS and MATS will allow Big Stone Plant and Hoot Lake Plant to meet federal air quality requirements.

On or after October 18, 2018 -$0.00075 per kwh
From November 1, 2017, through October 17, 2018 $0.00483 per kwh
